Webber didn’t hide the fact that he was upset with the outcome of the Malaysian race, where he was passed by team-mate Sebastian Vettel despite team orders directing both drivers to maintain their current positions, though he's made no suggestion he was considering quitting the sport.

It was Germany’s Bild that first reported Webber had been in contact with Porsche about possible interest in the new Le Mans campaign.

In addition, Red Bull boss Dietrich Mateschitz is reported to have said that it was possible Webber could leave the team, although the Australian had his full support for a 2014 seat at Red Bull.

Webber has been closely linked with Porsche for several years and even bought a 911 GT2 as one of his personal cars. He also sampled Porsche's last Le Mans winner, the 1998 911 GT1, at a Red Bull event in 2012.

Of course, Webber is no stranger to Le Mans. Piloting a Mercedes-Benz CLR prototype during practice at the 1999 24 Hours of Le Mans, Webber’s car spectacularly become airborne, back-flipping during both practice and race-day warm up events.

Should Webber end up leaving his Red Bull seat, we sure there will be no shortage of drivers eager to replace him. Some of the possibilities hinted at in the past have included current Lotus driver Kimi Räikkönen as well as fellow Aussie Daniel Ricciardo of Torro Rosso.
